在平面位置显示器和作为计算机终端的光笔图形显示器、综合显示器中,扫描线和矢量的产生是一个关键技术问题。本文针对上述系统存在的问题,叙述了一种适用于上述情况的新型扫描体制。这种体制采用计算机使用的累加原理,用常用的加法器构成矢量发生器。微处理机送来的数码经过电路确定矢量线段△X、△Y值,再经数码移位控制在进位输出端产生与输入数码一致的进位信号、经数-模变换和平滑电路成为扫描线或矢量。本文从原理、
The production of scan lines and vectors is a key technical issue in flat-panel displays and light pen graphic displays as integrated terminals, as flat-panel displays. In this paper, aiming at the problems existing in the above system, a new scanning system suitable for the above situation is described. This system uses the cumulative principle of computer use, commonly used adder to form a vector generator. Microprocessor sent digital through the circuit to determine the vector line △ X, △ Y value, and then by the digital shift control in the carry output and the input digital consistent with the carry signal, the digital-analog conversion and smoothing circuit to become a scan line or Vector. This article from the principle,
